A calendar is an important part of life especially when you have a really busy schedule. It helps us manage all the important things in our life whether its an office meeting, friendly lunch, children school event, or anything. Moreover, it helps us remember birthdays, anniversaries, bills, grocery shopping, appointments, and more.

But, different devices come with different calendars. Google products use Google Calendar, Apple uses iCloud Calendar, Windows uses Outlook Calendar, and so on. The chances are that you might be using a Google Calendar at home but in the office, you might have an Outlook Calendar. Then there are social media and other third-party calendars as well. With so many calendars, there are fair chances that, at some point, people often end up using multiple calendars. This questions the basic need of using a calendar at first place.
